.Tall 'whom it may conce/m:

'Be yit :known that I, lVAL'rnii J. Similar, e citizen of the United States, residing in the city of St.. Louis and State of Missouri, lieve invented a new and useful it'lotoiulioekingl Mechanism, of which the following is a This invention relates to lockinfji1 n1cc'hamism for motors, and isparticulnrly adapted for use as a lock for motor vehicle engines; and consists in the novel arrangement oi" parts hereinafter disclosed.

. An object of the invention is to provide mechanism of the character mentioned which will be ellieient to prevent the opcration of a'inoto'r when set, and which may heiconveniently and readily adjusted. v

`ill/llore specifically an object ol' the invention is to provide means for operating,r a lock 'bolt to seat the same in a keeper formed in the engine fly wheel, and nlso means to independently lock the lock bolt operating mechanism so that; the lock bolt cannot be withdrawn 'until the independent lock is manually' unlocked.

With these and ther objects, which will he apparent without specific mention, in view, l have designed, combined and arranged the seyeral cooperating parts or elements .iny the manner iereinat'ter described,

.reference being made, in the course of the description to the accompanying drawing, in whichlike characters ot relerence ind1- ente like parts throughout the several views,

' end in whiclr-w Figure l is a side view of the mechanism ot the invention, partially in elevation and partially in section, showing an engine fly wheel' mounted on the main driven shaft of en engine (shown in dotted line), and the lock holt cooperating with a keeper formed 4inthe periphery of the said wheel, and the operating` n'iechanisin for' operating the lock bolt, which ineclninism is supported by the 'vertical dash board ot' a motorvehicle,`

Fig. 2 is a view of the device, looking from the front ot 'the vehicle rearward. Fig. 3 is a. plan view ofthe mechanism. Fig. i

'is a detail view of key operated lock for locking the lock holt operating,r niecl'ianism, and Fig. is n View showing the rear :face oi the fly wheelL he lock bolt seated, and a portion of the lockholt operatnip,` mechan nism. y

,S have for the purpose of billustration shown my invention embodied In a motor rot' the lever S.

vehicle, the engine or motor of which is indicaled by A; said engine being supported ,by yokes l, carried bythe frame' or chassis l5. rl`he main driven shaft 2 of thcengine A, extends rearwardly, and `has fast thereon a ily wheel C, supported vertically, rearwardly ot' the dash board l) belowlthevehicle body. )l bridge 'or yoke 'll extends transversely ot' the frame B, and is' positioned superior-ent to -tlielly Wheel C. The bridge or voke il) is provided with a rectangular slot l Lformed therein, and positioned at the top or apex thereof.4 l ik sliding,y bolt i is mounted in said slot 3, and is adapted to seat in notches 5 formed in the periphery ol' the lly wheel C, when it is dropped to its lowered position by the mechanism lwreinatter described. At one side ol each ol the notches 5, is a projection or abutment (i. l have illustrated the notches 5 and the projection t,.ior1ned in a block which is bolted in recesses 7 formed in the periphery ot' the wheel C, and dianictrically positioned with respect to each other, lt will o l course bc understood that the periphery of the wheel C may be so cast asy to include integrally the said notches 5 and projections t3; but where niy device is applied to slructlires which include the usual ily wheels with smooth'peripheries, it will be obvious that the labor involved in adapting,r the wheels to cooperate with the lock bolt', will he lessened by utilizingthe coi'lstruction illustrated. The. integral eonstruction, however, would be preferable per,-

hops where the fly wheel C is constructed in the lirst instance with thc applivation ot' the present mechanism in view, as such n construction would he lstronger.

The mechanism llor raising,r and loweringr the lock bolt ft, comprises a lever 8, pivoted to a lug t), supported on the front ol. the dash hoard l) at about the lloor line of therehicle. One arm oft the lever 8,I extends rear wardly through a slot 10 in the dash boord l). The inner end of the lever 8 projects into a recess 1.1 formed in the upper 'face ot the lock bolt el; the depth f the recess ll being' ,greater than the vertical dimension In the walls ot the recess 1l are enlongaled slots i2; and lever 8 is provided with :r hole i3 adjacent to rits extremity. AA holt l-l, passing through said slots :ind opening, constitutes a pivot connection between the said lever 8 and the lock holt A hell crank lever l5 is pivoted to o 25. may be either luol 16, supported by the frontiface of the" dash board D, above, the lu'g 9. A link l? ispivoted at 18 to the lower arm of the lever 15, `and to the forward end lof the lever 8 at 19. The upper arm 4of the lever 15 isprovided with an enlongated slot 20; and eX- tends vinto a recess 21 formed in the outer end'of' a' rod or', plunger 22. A pin 23 passes throughregisteringfholes 24, in the walls of .lo'the 'recess 2l, and'through the elongated,

slot 20, thereby| constituting a'pin and slot connection between the plunger 22, and the vlever l5. The plunger 22 is arranged vto slide in .slots formed in the front and rear` wall of the case 25; said slots beingv arranged so that the plunger willincline slightly up- .W,a-rdIy. The. plunger 22 has a knob-,or handle 26 Von itsinnerend for manual engagement.' VAt one side -of the plunger22,

andmounted in the ease 25, is a key conto-be as follows :l Bymoving the plunger or 30 rod 22nwar'd1ythe lock bolt 4 is raised to a'. position above the-upper face of the pro-- jections 6,' and is locked in` its. raised .'posi#` tion bythe bolt 28 of the independent lock 27, seating in the notch 29. When the mech f anism is in this adjustment the ly wheel C ani-therefore, the shaft 2 of theengine' is free to revolve. After thev engine, has'been stopped, and it is desired'to lock it, the bolt 28 ofthe, lock 27, is. moved out-.of the notch' 40 29,'and'the plunger or rod 22 manually'l drawnf outwardly, lwhich drops the 'lock bolt 4.- lf-thelockv 27 is of t e spring type, the bolt 28 thereof will aut matically seat itself in the notch 30 in theplunger or rod 22. and will hold th lock bolt 4- down. In

-this position the 'lock bolt 4 rests against the periphery ofthe wheel C, and if the wheel C beltnrned in the direction of the arrow in an effort to 'crank the engine to start the opl eration thereof, the lock bolt 4 will abut against oneo'f the projections 6, and drop into the adjacent notch 5, thereby locking thevwheel C, preventing further operation thereof. Before the lock bolt 4 can be raised4 55 to release the wheel C, it ,is necessaryto re lease the -plunger or rod 22`by manipulation of the lock 27. l y

. The hood F of the vehicle covers Substantially all 'the operating mechanismy and by agees 4on, a bridge rigidly supported by the traine of the vehicle above said .nieinber, a lock bolt operating through 'an opening in said bridge, an arm supported above said bolt and being connected to 'said bolt,loperating -connectionsfor raising vand lowering said arm anda lock device for locking said. connections, substantially as specified.

2. In a lmotorvehicle, the combination with an, engine having a rearwardly extending shaft and .tly wheel fast thereon a lockfbolt supported above said ly-whee",L keeper, devices arranged in the periphery o'f said 'tly-v'heel and adapted to cooperate with said 'lockI bolt, an, arin supported. by the dashboard of the vehicle having pin and -slotj connection "withsaid lock bolt, a 'hell crank l,lever supported above said arm,- a "linlr' connecting one arm: of the bell crankv lever to saidarrn, `and a plunger. extending `throughl the dashboard of the vehicle, and accessible' from the drivers sea-t thereof, for operating said bell crank leverfand thereby raising and 1lowering saidl lock bolt through 'the connections ei'ectively to lock and unlock v the said Hy-wheel, specied. l
